People look at a bluefin tuna displayed at Sushi Zanmai restaurant near Tsukiji fish market in Tokyo Saturday, Jan. 5, 2013. The bluefin tuna sold for a record 155.4 million (US$1.76 million) at a Tokyo auction Saturday, nearly three times the previous high set last year � even as environmentalists warn that stocks of the majestic, speedy fish are being depleted worldwide amid strong demand for sushi.
